Portable latrine

Abstract

A portable latrine includes an annular seat that has an opening formed therein and a lip formed with a perimeter of the opening that extends downwardly and orthogonally from a seat top surface. A biodegradable sack has an elastic open top end for fitting beneath the seat opening. The elastic outer edge is adaptable between extended and retracted positions and is seated against and on top of the lip for suspending and supporting the bag therefrom. Independently pivotal support legs have opposed ends that are positional adjacent to a seat bottom surface and on a ground surface, respectively. Hinges and clamps are conjoined to the seat bottom at opposed corners thereof. Each clamp is situated adjacent to its corresponding hinge. Straps are connected to selected hinges and include a D-ring conjoined thereto for receiving a backpack portion therethrough such that the latrine can be attached to the backpack.
